I use the following a lot:
- Nextcloud for files, calendar and contacts
- synapse + a few brudges for IM
- mail server
- tandoor for recipes and grocery shopping lists
- gitea
- wireguard
- miniflux
- rmfakecloud And from time to time:
- jellyfin
- wallabag
Tandoor is imho somewhat overlooked and really nice.
Can confirm, am using the remarkable tablet to read a lot of academic papers. The only thing to keep in mind though is that the best experience is that apparently you need good enough vision to be able to read the article without zooming, some people I know struggled with this. However with normal sight, I basically only zoom to note something in the article if there is not enough space to note it down otherwise.
